Hi all... well, I'm getting there slowly but surely. I've attached an azimuth scale to the Dob's ground board. Now I need to cut out a small section from the top board through which I can sight the scale. Some questions if i may:-

1. Should this cut-out be made at the very front of the top board directly below the centre of the OTA?

2. To align for azimuth, do I centre Polaris through the eyepiece and, whilst keeping the OTA where it is, turn the ground board independently until the zero/zero point appears at the front?

3. I've ordered this digital inclinometer which should be arriving shortly

4. I plan to use Stellarium to get the alt/az readings as I can access it on a PC close by the scope.

Thanks in advance for any help.
